[clang][bytecode] Check primitive bit casts for indeterminate bits ( #118954 )
...
Record bits ranges of initialized bits and check them in
allInitialized().

Reapply "[clang][bytecode] Handle bitcasts involving bitfields ( #116843 )"
...
This reverts commit 54db16221c92eb52efbea90ad5b5d2a1d00cda3e.
Check for existence of __SIZOEF_INT128__ so we don't run those
tests on targets that don't have int128.

Revert "[clang][bytecode] Handle bitcasts involving bitfields ( #116843 )"
...
This reverts commit 4b5e7fa4de54e00df007ae5e2675393fd046aa59.
This breaks builders:
https://lab.llvm.org/buildbot/#/builders/154/builds/8464
I guess some more testing on 32 bit hosts is needed.

[clang][bytecode] Handle bitcasts involving bitfields ( #116843 )
...
Copy the data one bit at a time, leaving optimizations for future work.
Adds a BitcastBuffer that takes care of pushing the bits in the right
order.
